PR10019: --skip-badvars to suppress run-time memory errors too
* NEWS: Note this change.
* hash.cxx (find_script_hash): Add s.skip_badvars into hash.
* translate.cxx (translate_pass): Emit STP_SKIP_BADVARS.
* runtime/loc2c-runtime.h (DEREF_FAULT, STORE_DEREF_FAULT): Provide
dummy implementation if STP_SKIP_BADVARS.
